With two of the last fragments of fen - Woodwalton Fen and Holme Fen - under threat, plans to link the two nature reserves began in the late 1990s.
The Great Fen was officially born in 2001. It was named after a large area of wild fens shown in the same area on local maps, from the days before the land was drained for farming.
In 2001 the Great Fen partner organisations came together, forming a Steering Group Committee and employing the first Great Fen member of staff.
The Great Fen was originally a 50-year vision, but thanks to much hard work and the support of many individuals and organisations, major milestones have already been achieved.
After just over a decade, more than 50% of the land of the Great Fen is now owned by the Great Fen partners with 2140 acres (866 hectares) of land in restoration and 3750 acres (1519 hectares) managed for nature conservation (including the two National Nature Reserves of Woodwalton Fen and Holme Fen).
The Great Fen also delivers a comprehensive education and community service, has ten members of staff working on the ground, and is supported by more than a hundred active volunteers.
These achievements would not have been possible without the support of many people and organisations - well-known supporters such as HRH Prince of Wales and Stephen Fry, funders such as the Heritage Lottery Fund, individual supporters, businesses, staff and volunteers delivering work on the ground.
Here are a few of the historic highlights in timelines.
How the land has been restored over time and the wildlife that has benefitted.
Schools and community projects, and the creation of new facilities for visitors.
An increasing national and international profile.
